this guy has got to be the most advanced logic board repair engineer in the world, i do the same or similar work and i am so so jealous how advanced you are and skilled i dont think ill ever get this good , on the other hand i wont do CPU/GPU BGA jobs dont have the skills nor the equipment but just wanted to drop a line to give you the respect and credit you deserve
Isn't there an apple repair guy in NYC that might be equivalent to this guy?
I agree! I was amazed to see him repair a via under a GPU BGA pad by drilling a hole through the PCB and running a botch wire. And get this... The botch had to reach a trace on the 2/3rd layer so he found a spot on the trace path where he could sand down to it without hitting other traces. Best repair work I've seen in years and he makes other UA-cam electronic repair channels look amateur. Total master.
This guy is awesome.
But I would have to be an expert in repairing and would need to know all repair technicians which exists to rate him “most…. of the world”
What a gut-punch! 2000 Bucks down the drain because someone thought using Liquid Metal is just like using thermal paste and didn't research proper usage first. Very expensive learning experience and a quite effective cautionary tale. Too bad about the Card - my condolences to the owner despite all else.
Whoever learned this lesson clearly needed it.
Hey, at least they learned it now. Lord knows what the -90 cards will cost 5 or 10 years from now, would probably suck a lot more to have to learn it then.
People say it's a very expensive 2000 dollar mistake but if the guy has to buy another 4090, then it's actually a 4000 dollar mistake. Oof
@Thomas B I'll counter with, what goes through Joe Brandon's mind? Nuff said.
@Thomas B I'd assume the owner wanted to integrate the GPU into his/her Watercooling loop - which is not too problematic if done correctly. Why on earth they decided to use Liquid Metal still boggles my mind...
I find these kind of repair videos to be like therapy, very relaxing and satisfying.
To watch someone do effortlessly what would make you give up. I have a dead ASUS motherboard from trying to remove the backplate to install a CPU fan, the screwdriver sliced through some trace lines. The time and effort (after putting in time and effort) and failing wasn't worth the cost of the MB.
This guy could have it fixed faster than Alice could serve up minute rice.
But yeah, very relaxing and interesting to watch!
i have done a lot of soldering in my life and i know my way around circuit boards, but what you do on this tiny components is like pure magic to me.
keep up the great work, i love watching your videos.
Liquid metal is always the best friend of repair technicians
I’ve been doing component level repair for 20 years and I’ve never been close to what you’re doing here. 2 layers, maybe 3… very impressive even with the nice tools. A true master
im very hesitant to give spoilers but as for now they sounds like an iem, thats it, i dont hear hopes
thats no mastery. gpu rapair is easy, the most special stuff is in the core. and they cant repair it, only change. and u can do it easy, with the right tools ^^
@@fellpoweryes, that's why this is so common
@@fellpower Care to post a video?
Did you see the video where he fixed a trace connected to a via at the GPU BGA pad? He also had to hit it's trace a couple layers down mid PCB without hitting other layer traces.
Some bad descision were made there, but an absolute joy watching you work on gpus :-)
which ones?
@@Radek__ using liquid metal when you dont know how.
@@kimborch8547 oh I thought that you are saying about Kirs, that his decisions during service/maintenance were bad.
@@Radek__ Oh, ok. No no, Kris does some amazing work on this, as well as other cards.
This channel is an absolute gem. Thank you for this video.
Too bad that the card was unsalvageable.
AFAIK 4090s have only 2 main 12V power planes. 1 for ALL the Vcore VRMs and 1 for ALL the memory power. A fuse for Vcore that wouldn't blow under regular operation would have to be rated for like 50A. MSI does put a fuse on their memory 12V power plane but they are the only manufacturer I've seen do that and they also don't have fuses for Vcore.
Wow, I did not know this. Thanks for the info
my MSI Suprim X (air cooled) died after the first day (no experiments, it was in original condition). 😞
Big ouch. Liquid metal on the gpu for 2-3°C better temperatures is not worth the trouble.
This!
Liquid metal for 1k $ less in your pocket :D
@@madmartigan9720 The cheapest RTX 4090 from Gigabyte that I've found goes for €1899 where I live (which exchanges to roughly $2014 as of this post), so that's well over $2k down the drain (especially if you count the extra cost for the liquid metal, shipping for all these products, etc.).
It's never about the thermal compound used anyways, its about how much heat the cooling can dissipate, the bigger the gap in dissipation temps the faster the temp is dragged out of the chip.
But too large and you cause condensation from moisture in the air.
it's not "2-3c" more like 5-15c
Thank you for publishing another video :D
I really enjoy watching professional level repair even though I repair circuits only as a hobby.
On the other hand, I would never consider repairing after such a mess from liquid metal, if I had such expensive tools.
thank you its always fun and informative to watch your videos , hope there are much more of them
By night, Kris plays in a band called "Gallium Corrosion".
The genre is a fusion of Liquid DnB and Death Metal.
I'm developping an addiction to "GPU repair videos"
Really enjoyed that, thanks. That gallium liquid metal is so dangerous in the wrong hands.
For water cooling GPUs, it's not necessary to use liquid metal. Just get Thermal Grizzly Hydronaut. It is more than enough, with good radiator setups and fans you will not even reach 70°C on the hotspot, ever.
“But it can give me 2 degrees lower temps!!! That so much more performance I can get!”
I like waterblocks. Always have and always will, just because of the aesthetic and the noise levels.
Liquid Metal is only useful for delidding and relidding a CPU die.
Even though I get watercooling your card it's not even really necessary with 4090's from a temperature perspective, they're all so overbuilt.
Don't use Thermal Grizzly thermal pastes. Just use Gelid Extreme. It is literally the exact same formula, doesn't cure or dry out like Thermal Grizzly, and it costs only 20% the price of Thermal Grizzly.
This guy was just to dumb to use it. He didn't even used any protection for the transistors around the CPU
Why even bother if you are not going to go all the way?
Damn, and I was scared to replace the thermal pads on my 3090 FE with better pads (though I finally did replace them without any issues) - I can't IMAGINE murdering an even more expensive GPU with what appears to be a completely unnecessary mod. That sucks!
Especially as you can buy reassembled water block gpus.
Only an idiot does it himself and void warranty for water block.
@@romangruber6685 Hey, here's the idiot, who do this for fun and cause I know what I do. I optimize my systems for low temp, low noise and as much power, as needed. If you know what you're doing, it's absolutely fine and doesn't harm. My 1080 OC was running 5-6 years with 30% OC, undervolting and a max temp of 46°C for several thousands of hours and life's till today. Also my i7-6700k run the same time, mostly stock, Direct-die and a max temp of 52°C in a ultra-silent system. That's what I'd like to achieve.
Actually I'm running my i9-13900k (E-Cores deactivated, cause my screws on the contact frame are to short) and a 3080ti in a silent system with max temps at 60 on the CPU and 50 on the GPU. I'm waiting for my Direct-die upgrade kit and some other parts and then I'm going in the same direction, but without an aggressive OC, cause it's not necessary at the moment.
I'm enjoying such work and love to optimize the systems, as much as possible.
Also liquified some laptops, with dedicated GPUs, which got a new life, cause before, they had temps nearly instant at 100°C and couldn't utilize nearly half their power.
@Thomas B Why?
@@PsychEngel Same question WHY what do you gain from it from my experience basically next to Zero gain .
@@petenikolic5244 I can't see his answer anymore. Do you know what he wrote?
Awesome video. Great camera work.
Very nice video to look at. You explain very good aswell.
Some people are unqualified to buy PC hardware, the owner of this GPU is one of them
"Very good card, it was a very good card, now it's nothing" 😂😂😂
I love your style, calm voice and demeanor. Good audio, good camera work, all around excellent. I can watch you do repairs all day
Is it a declaration of love and marriage proposal?
it's really fun to watch, and maybe you can still take one or the other with you. but I wouldn't dare to do it myself, first learn from someone like you who can really do it. good work
Mal wieder ein sehr interessantes Video! Ich habe die Videos schon ein wenig vermisst :( Vielen Dank, dass du dein Wissen weiter mit uns teilst. Bester Mann!!
You are a wizard! Thanks, Kris!
putting liquid metal on anything is a recipe for disaster so putting it on a us$2000 gpu is like buying a ferrari and sticking tnt to the exhaust
Finally, Long time no see, lets hope for long live video ☺
the godfather of cardrepair, great video
Brilliant stuff!
Some bare minimums when using liquid metal IMO, cover the entire PCB with protection (I use paper stuck down with electrical tape) while applying to prevent accidents. Coat any caps/resistors on the die using nail polish. Use a very small amount of liquid metal, work it out using the supplied spudger. Get some pre applied ahesive open cell foam gasket strips from your local hardware store and apply around the chip so if any liquid metal escapes there is a good chance it will be caught by the foam.
Or just you know, dont use liquid metal... lol
don't use nail polish, use proper electrical conformal coating - nail polish contains moistourisers, vitamins/minerals with penetrators, etc.. since it's meant to go on biological matter, which may end up corroding the components over time and heat cycles. the £2 you save on using nail polish is not worth it
Or you know look at the ingredients?@@glebglub
@@glebglub Good advice! Can conformal coating be purchased in small tubs?
@@eudaimonia9386 small tubs, big jugs, sprays, toothpaste-tubes, syringes, pens... in other words yes lol. some are UV reactive though (like a solder mask) so make note if it is an needs/comes with a UV torch, or have a 24-hour cure period due to being evapourative meaning it may dry up like super glue/caulk once opened, 2 part epoxy, etc.. I honestly forget which one is "best" for this use-case (guessing silicone-based but don't quote me on that, it may be acryllic afaik), I just remember you don't want to go *too* thick else it wil impede its ability to radiate heat, but the same can be said about nail polish anyway
You're a modern age wizard; You show, and tell... We're very impressed as per usual my good sir :)
True magic.
Lesson I learned: Never mess with liquid metal.
That's like saying: lesson learned, never drive a car, after an accident.
Bin immer wieder beeindruckt, wie man an so filigranen Bauteilen arbeiten kann. Ich arbeite in einem Bereich, in welchem man scherzhafterweise alles unter M12 als Feinmechanik bezeichnet.
Next level repairs !
Excellent explanation.
Regards.
I see people in forums and in comments talking about using liquid metal, like it’s something to be taken lightly, I’m not using liquid metal on anything I can’t isolate. So that if it leaks out, no damage can be done. For example, on CPUs I have delidded, I always seal up the IHS so no liquid metal can escape. And I’m 100% not using it on a GPU. It’s not worth the risk for a 10C temperature reduction that might get me an extra few MHz
"This is very bad" + the cost of the card = a very bad day for the owner. :O( The tangled webs we weave. Thank you for the video. Top Notch effort!
I am happy to see again doing proper love to those poor graphics cards, I have learned a lot from your channel you are master!!!
I'm just blown away... I understand modifying your hardware etc but when it's brand new like that, I guess I've just never had the money to afford losing to even consider modifying something that is worth thousands of pounds and still in warranty.
Early deaths of any given hardware in the first 3 months are are anything but uncommon... this is why you have warranty. It's good to get past that stage at least.
But it's more fun to wait till hardware has all its warranty lapsed and has as little residual value as possible and then go WILD.
Its like investing, dont do it if you cant afford to lose it all
I have put 240w and liquid metal and custom water on a brand new ryzen 3950x and got into the top 20 in the world in some benchmarks for that model of CPU, though over time more dedicated overclockers beat me. Gotta be fast if you want you name on top of the list of fastest CPUs even for a day. Probably could have done top ten if I delidded it. Maybe when I save up enough pennies to buy and delid a ryzen 7950x with some drr5... or 8950x even...
It's a bit scarier to do this to GPUs since they cost more and have more vulnerable parts near by which are slightly more challenging to protect. I usually just cover everything nearby with liquid electrical tape so any spills can be peeled off. Saved a laptop from some clumsy fingers this way.
I have to click like even though it was a sad case. Expensive lesson for someone I guess. BRAVO as always Kris and thanks or your help. PEACE\/
When I had a liquid metal spurt from the syringe that got under a memory chip on a 1070 MXM that luckily only caused a code43 in device manager, I managed to get it out using copious 90+% isopropyl and compressed air, outside, so the LM ended up somewhere in the backyard. Card still works. I have found isopropyl and paper towel is good for surface cleanup
I've washed cards in soapy water before that had nicotine stains that I got cheap. It won't hurt it any but like you mentioned, use alcohol on it then compressed air real good under all the SMD parts. Alcohol will mix with water and evaporate much better, and air drys it out. The key is completely dry under all the parts, GPU included. Having a air compressor to do it is recommended though... Lol.
Why people nowadays feel they need to liquid metal everything? All the old and safe(r) ways still work very well, folks!
All the 4090 are well cooled, too much, the only reason to put a water block is to get rid of the enormous cooler and do a water cooled system, in top of that liquid metal always is risky because is conductive and corrosive for a tiny small amount of degrees of cooling.
Why do people even need liquid cooling on cards with such good cooling ! Idiocy.
@@1983Konstantin space, or they already have a custom loop and want to integrate it into it. Otherwise it does not make sense as enough ppl in the comments stated.
@@1983Konstantin Yeah it is becoming very unnecessary given the size of these cards, the fans they use are large and quiet.
The space saving advantage does still exist to an extent but it's not like a radiator and all the hoses etc are tiny, it just seems like water cooling in general does not offer quite the same advantages as it once did when graphics cards in particular liked to pretend to be hairdryers.
Same question to all the people deliding cpus that work perfectly fine.
I recently watercooled my Gainward 4090, instead of Conductonaut (Liquid Metal) I now used MX-6, performs really good and no risk as shown in the video.
A little too expensive to experiment with it haha, although I always was very careful, tape off areas etc etc, never had problems but this time I was naaah, let's just use MX-6.
Wow watching you doing these repairs is mesmerising and satisfying
My 4090 after 6months gave up stopped giving monitor outputs. ( MSI 4090 GAMER X TRIO)
I wonder what caused that lucky it’s still under warranty 🙏
The customer was successful. That card will stay cool forever.
I am big fan of yours. Please make video on regular basis.
@krisfix-germany can you list or make a quick video on the tools you are using ? thanks if you read this.
real nice wick broom. do they have different sizes
Hello KrisFix, thanks for another great Video. Is the missing Fuse on every 4k Series GPU from Gigabyte? I will get a 4070 Ti from Gigabyte (4070 Ti Eagle OC) and a bit concerned about it now that there is the same Situation on it? Thank U very much 🙂
Definitely a Boss with this type of work
Liquid metal sooner or later means only problems.
In my opinion it is not worth to take such a risk.
Agreed, and the Gigabyte RTX 40 cards have very good temperatures with the stock paste and pads anyway.
it doesnt even give you more headroom anymore either. i put my card on the aquacool gpx block and LM and it didn't give me any more boost bins or headroom than the factory air cooler lol, and that's even with a nearly perfect seat of the die to the cooler because i only have 7-8c difference from gpu temp to gpu hotspot, which i never achieved before. at least it runs nearly 10C cooler, but kingpin kpx paste wouldn't be far behind and is way less dangerous
I've come to this conclusion as well... A few degrees cooler isn't worth it
@@GhostMotley never seen mine above 65.
In my case LM lowered hot spot by 10*C and delta was about 12*C instead of >20*C after furmark. It also allowed my GPU to go 200-300RPM lower on same load with still lower temps, so it depends on person :P
I used LM once with a delidded 4670K. But I did my due diligence in how its done, masked everything, didn't overuse and it worked for several years.
Great job, man😀Tell me, how do you remove liquid metal?
I suppose on the plus side, you could use the PCB itself to repair another card (well GPU chip anyway). If someone had massive PCB damage this PCB should still be intact.
Hi. Könntest du mal ein Video machen zum Thema Mods/Mats? Wichtige Befehle oder Einfach Benutzung?
He wanted to decorate the peacock, and now the peacock is useless.
I love when clients break their things then come to me but this one, I would not even try to repair it because the amount of work is simply too much. On top of everything, the client doubled the bad behavior and tried to "fix" it himself/herself.
I do not do any second repair attempts.
Pay me respect and bring me something which was not opened for repair before.
Liquid metal...the gigachad method of destroying your expensive parts.
Just so satasfying to watch
can you tell me the value of the capacitors that are usually used above the gpu, I have missing 1 pcs when cleaning it
Hello sir, what temperatures approximately you use to remove the chip top and bottom?
Looks to me like somebody tried to apply liquid metal like regular paste with the drop on the middle technique.
No liquid metal will not spread by itself over the surface, placing a drop will only cause the metal to squish itself out, liquid metal is great but it has to be applied correctly.
Finaly new video!
Very enjoyable vid, such a shame this card was not repairable, I wouldn't ever risk liquid metal, stick to good ol non conductive thermal paste :)
I have used liquid metal on so many applications I even did liquid metal on my reference Rx 6900 xt when it was brand new coated $1000 and just released. Liquid metal isn't that dangerous if you know how to use it and take some precautions.
I bought another MSI Rx 6900 xt trio x, put a waterblock on it and liquid metal. This time it was the closest I got to failer but my precious saved me.
I cover the small components just around the die with multiple layers of nail polish. When I was spreading the liquid metal I actually spilled a little over the edge of the die but the nail polish did its job. I removed as much as I could but there are still a little bit stuck in the nail polish but hey 2 years later the card have never had any issues.
So my advice to liquid metal users:
1. Coat the small components around the die with clear nail polish as thick as you can get.
2. Use both hands to push the liquid metal out.
One hand holds the tube, and with the other hand you use two fingers to hold around the piston 1 mm from the tube, that way the tube acts as a stop and you don't overspill. Push 1mm, move your fingers 1mm up and repeat until it starts coming out.
Also if there comes to much all of a sudden you can instantly retract the piston sucking back the liquid metal.
If you use that technique you will never spill liquid metal.
Or I just put the LM straight on to the tip of the cotton bud then on to the chip!
@@samtaliano6814 Not a good idea because now you have to carry exposed LM over all the components, if you put too much LM on the tip and it drips or you drop the cotton bud you are fucked.
In the beginning I used a coffee plate to put the LM on first and then dip the cotton tip in it. But as I said carrying exposed LM is super scary because one day you might fumble and drop it.
With my method you can't mess it up, i even applied LM on my CPU today.
@@HenrikHvalpen that's what your other hand Is for as a cup underneath the cotton bud!
I'm still not a fan of that method because it requires a lot of movement. When I applied it I am standing completely still and only focusing on how much coming out of the tip. Then when the right amount has applied I pull back on the piston making sure nothing is coming out. Then I can relax and move around safely.
You won't convince my to do any other methods. I have gone through 3 tubes of liquid metal so I have tried it many times at the moment and I have never had any incidents. And it should stay that way. 😉
@@HenrikHvalpen yes of course!! I was always iffy with how the LM came out of the syringe but yes you described the way to get it out of there!!
Alternative video title signs that owner has too much money and not enough sense
Could you tell us please what we can do to clean the card/PCB (like a motherboard too) if we get liquid metal/ thermal paste on it by mistake? (what to do in such cases?) if that's something we can do without expensive professional-grade equipment that is. I would love, if you wanted to, make a video on topics like the one I asked too: in terms of what to watch out for/ how to prevent your card from breaking/ being irreparable :D (I am sure you can think of many customer errors that could have been prevented)
What is that tool called? It looks like a brush or even a broom, but it's a part of your soldering iron.
Can you clean gallium with a sonic bath?
Or evaporate it?
I was just getting ready to purchase a 4090 and Im glad to hear about this gigabyte issue about the lack of fuses. With your vast experience and knowledge which of the 4090 cards manufacturers would you say is the best build quality? I have read msi but your opinion would be of greatest value. Thank you for your time and providing this type of content and information to us.
Techpowerup has PCB shots of most cards. From a cursory glance, the Palit/ Gainward Gamerock OC looks to be the most "fused-up" 4090 that has a clockspeed above 2600
Classic case of "verschlimmbessern".
15:00 is like turning the RTX back on :D
I find it hard to believe that people use liquid metal so carelessly. And a 4090 with a water block doesn't even really need it.
Yep. Thermal paste keeps the hot spot under 70°C, the normal GPU average temp doesn't even reach 55°C... Why use liquid metal?
I have not done a lot of testing so far.. But my 4090 has never even broken past like 60°C while I was playing Cyberpunk on max everything. That thing is cool and quiet. I don't see any real reason to put a water block on that card unless it's to save space and / or flex.
A 4090 doesn't even need water cooling :-)
@@BenderTheOffender depends on your tolerance for fan noise
@@chincemagnet A decent gaming headset can work wonders 😉
Can you harvest the vram to use on another card?
How much would this cost to fix?
Is it possible to ultrasonic liquid metal?
Have plans to build a rig myself for the first time in 20 years so have been studying up by watching a few well known content creators who know their sh*t, so far I know enough to not mess around with liquid metal, it's conductive and corrosive, it also has a habit of solidifying with time and needs reviving. For the sake of 2° I'll stick with thermal paste, if I ever brain fart and use liquid metal on the most expensive parts of my rig you can be sure I'd let an insured professional do it instead.
Hi, i have a Gigabyte RX 6800XT that display some thin lines when i'm playing any game or even when i'm stressing it with furmark, please advise if is worth repairing the card.
Oh man, bad day for a guy, always great to watch you work tho!
19:35
so Gigabyte uses low cheap power stages for the 4090 cards.
hhmmm may not soo bad as a main thing, but maybe it has a crush in 8 years then . . .
I'm sorry, but this customer should be rewarded with some sort of diploma. They did not even try to cover the smd components surrounding the core with nail polish or other insulator, and they used the wrong tip which made way too much liquid metal spray out of the tube. As others have pointed out before me, this is a classic example of more money than wits. Hope they have a hard time recovering financially from this, so that the lesson sticks.
YOu have really a lot of Galium damaged cards in. wondering if people use a low quality liquid or just put to much in, their cards look often soaked in it...wondering how it splashes so far away from the gpu. love your videos, i love watching them
thats why i didnt bother to use "liquid metal" paste on my 4090, too high risk to fuck up the card
Hello. I have a MSI Supreme 3090 that RGB keeps flashing when under load and will shut down or restart PC instantly (no critical temps on logs). It seems to boot and work in windows, you think it would be fixable?
I really want to repair this card but in my country I don't trust the repair shops
I noticed there was a crack on one of the memory chips.
I've been building and modding PC's for many long years now, I have seen liquid metal come and go from fashion and usually after a great many folks have murdered their electronics they have fallen out of vogue. I think the concept is right on the money, however we need a medium that a) doesn't munch other metals b) doesn't conduct angry pixies but c) acts exactly as a stay liquid thermal conductor. I am thinking some of the inert silicone compounds would be well suited, we know silicone is not destructive to other materials and can be made electrically inert fairly easily too, keeping it liquid so it doesn't solidify would be the key here, prob infused with nano-plastics or ceramics would give it a more stable rigidity too. Gallium is an incredible metal but will munch virtually every metal and alloy out there, even if it doesn't break metals down it will contaminate and weaken to a point of uselessness very quickly. Gallium is also incredibly adept at escaping constraints and when its cooked up produces an even nastier oxide which is how I think the stuff is escaping from PS5's, heats up, oxides, escapes as a semi gas, cools down, becomes liquid again munch munch munch bang.
Gallium has a thermal conductivity of 29 W/m K, it's actually not all that ideal as a cooling medium but some people think because it's liquid and easy to apply it must be great to use because they see it mentioned on some YT tech channels.
Copper has a thermal conductivity of 400 W/m K, which is why it's perfect for heat sinks and for the lids of CPUs/GPUs but it's not "liquid" and not easy to apply.
But idiots will always want that 2-4 degree C "improvement" for bragging rights while using materials which are "convenient".
The best thermal conductor to use and is very malleable but chemically inert is Gold with a thermal conductivity of 320 W/m K in the form of thin gold foils, but most people don't want the expense and the inconvenience.
Hey Kris kannst du dein Mats/Mods Image veröffentlichen also den Link wo du deine Version her hast wäre dir super dankbar
Welcome back :) What a horror piece.
Impressive how much work you put in just to prove whether or not the board and chips are good or fried.
The repair is not failed, it's just the cost to repair might be as good as buying a new one.
Kris, very much interested on your observation on these disconnected pads 12:50 .... as there are many users having issues of crashing with their 4090s ... could this be a wide spread issue.
Nice video. You are the hope of many GPU users and the inspiration of many ppl willing to repair this kind of products. Thank you a lot.
I was wondering if there is a fast way to know if the GPU do works or not (as it was done with the RAM modules) In case someone gets one from eBay or similar.
There is no foolproof way to tell except to plug it into a system, boot it up and do some elementary testing.
If you're dealing with ebay you 'll need to check if there is a "money back" guarantee to cover you if the card doesn't work, if you're doing as cash transaction I wouldn't bother buying unless you personally know the seller. Too many stories of people being sold junk and the seller vanishing into the distance as soon as the transaction was was done. Kris did a video on such a case with multiple similar failures from a private seller who may have storied their cards improperly and suffered damage from the environment.
@@glenyoung1809 thanks for the answer. I wasn't as clear as I thought. I meant, since it's becoming easier to get spare parts to replace damaged or defective parts, specially VRAM modules and Kris tests them measuring the voltages before soldering them, I was wondering if such test or similar tests can be made to the GPU part before soldering it to the whole system.
@@nowaywithyoueveragai Obtaining genuine electronic components would be the first challenge.
Three ways to source such parts,
1) OEM-going directly to the source to buy new parts, no guaranteed to happen since a lot of suppliers only sell in bulk quantities.
2) Going to the AIB, this is unlikely as well, unlike car makers, GPU makers have no incentive to sell parts to end users for DIY repairs or even modding of their boards.
3) Salvaged boards from dead GPUs, this might be the most likely source of parts for DIY fixes.
Options 1 and 2 can guarantee you a functional part, option 3 us the riskiest and you can never be sure of its quality or functionality.
Also option 3 is subject to a growing problem, counterfeit parts which are appearing on the market because as you stated DIY repairs are becoming possible.
As to your question of testing, it might be possible but from my limited understanding most electronic manufacturers and even the AIB board makers have specialized testing equipment and internal procedures in the form of service manuals to test boards and parts for defects.
From what I’ve seen of Kris’ testing and repair setup he’s a professional and has some high quality gear to do such repairs, he certainly isn’t what I would call a DIY guy. He also seems to have proper diagnostic software which I don’t know if he created himself or purchased elsewhere.
Testing VRAM would be tricky as is testing the GPU itself to determine its viability without having a pin out map of these parts, not something I’ve seen to be readily available outside of AIBs, although I suppose the VRAM part you can probably get ahold of the spec sheets from the manufacturer website.
I'm trying to find aa video about a 3070ti repair with bad memory because the heatsink wasn't covering the whole memory chip in an attempt to save money using 3080ti and 3080 heatsinks, but I can't find it anymore. Has it been deleted or am I imagining it and have gone crazy? The thing is I remember so many details, like the gpu beins asus, that I don't think it's my imagination.
Godlike as usual . you also have my card for the second time ... because i was stupid 2 times to spill water over it
just out of curiocity, do you also repair motherboards or just grapichs card?
Yes
13:50 I wonder IF it is a damage from reassemble with the waterblock,
the vram thermal pad thickness is set with thermal paste in mind,
liquid metal is most likely thinner than thermal paste,
too much mounting pressure lifting the outer part of the vram's?
Mal so ganz ehrlich gefragt, was kostet denn so eine Reperatur ungefähr bei dem Zeitaufwand bei euch? würd mich mal interessieren so ungefähre Werte :)
my parents use to tell me before... "dont play with fire" so now Im gonna advice the next generation, dont play with "liquid" metal :)
😂
...But I love playing with Gallium and destroying Aluminium objects!
What kind of tool are you using form removing the liquid metal? Is it some kind of pump?
I had the same question - would like to know
I suspect it is one of the alcohol squirt bottles but empty. He is pressing and then releasing for suction
I saw another guy use a liquid metal syringe, the same one the Conductonaut comes in, to suck it up
just a pipette probably
2:28 Because of the simple reason that they would earn more money not to since there is higher risk that it will then be so destroyed that the customer need to buy a new one instead of be able to fix it if it has fuses everywhere.
